SPECIFICATION forming part of Letters Patent No. 592,216, dated october 19, 1897.

" A Eppiioaiopiea .4pm 21,1897. serai N9. eeaievfoio man.) Y

T0 all wiz/loira -if may concern,.-`

Dominion of Canada, have invented a new and Improved Churn, of which the following is 'a full, clear, and exact description.

This invention is a churn with a reciprocal dasher, serving to create a current of cream around a reservoir, which may contain hot or cold water 'to regulate the temperature ofthe cream. ,v L Y This specicatiomis the disclosure of one form of myinventioh,r while theclaims define the actual(` scope'of .the conception.

Reference' is to be had to the accompanying drawings, forming a part of thisfspeciication, in which similar characters of reference indicate corresponding'parts in all the figures.

Figure 1 isa section of the invention on the line I I of Fig. .2. Fig. 2' is a section of the invention on the line II `II of Fig. 1, and Fig. 3 is a section of the invention on the line III III of Figi V1.u

A base-boardv 4 is provided with cleats 5, arranged in a square figure and holding the lower end of the churn-body 6,"which is a vertically-elongated four-sided structure, with a metallic base 7 rested flat uponthe upper,v

side of the plate 4 and having iianges sunken in the lower edges of the sidesof the bodyfi,v

by which construction a hermetic chamber is formed. The top of the body 6 is closed by a lid 8,/

having a slot 9, through which the dasher! rod 10 is movable. The dasher-rod 10'is piv' oted to an operating-lever 11, themtransverse `head 12 of which is mounted in standards 13,v

respectively carried in diagonal positions by sides of the' body 6. The lower. end of the rod 10 carries a transverse head 14, the ends of which respectively carry bars 15, running parallel with each other and spanned'at their ends by cross-bars 16. Pivotally mounted between the bars 15 are the dasher-plates 17, which open downwardly as the dasher moves upward, and as the dasher moves downward the plates 17 close against the cross-bars 16.

The lower end of the dasher-rod 10 has a removable plate 18 covering a thermometer 19,`

the bulb 2O of which is continually exposed at the lower end of the plate 18. The plate removed to expose the tube Be it known that I, JoHNBENNETr, ofy Lyndhurst, in the Province of Ontario andl of the thermometer when it is desired to note the -indications thereof; but normally the thermometer is'covered to prevent it from being `engaged with the cream and butter within the churn-body 6. A hollow partition 2l has side flanges 22 .respectively running in vertical`V grooves 23formed in the inner 4of the churn by means of an apron 26 to which therpaslsa'g'elvZ leads, ,Agcleat 2,7 gis f carried by the'rear wall of the body 6 of theachurn and in position to be engaged by the ledge 28 at the upper portion of the partition 2l, whereby the partition 21 may be supported in proper vertical position.

yThe operation of the dasher within'the churn causes the cream to circulate throughout the body in a manner indicated by the arrows in Fig. l. By means of a feed-nipple 29 the hollow partition 2l may be filled with liquid at such a temperature as will properly regulate vthe temperature of the cream. The

agitation of the cream against the partition effectually churns the cream, while the peculiar construction of the dasher tends to make the circulation of the cream perfect.

'Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with the churn having a body portion, of the hollow partition within said body portion, said partition providing passages at the top and bottom of the body and through which the cream may circulate, and having an inlet-opening for water, whereby to regulate the temperature of the cream.

2. A churn having a body portion, a hollow partition run longitudinally within the body portion and dividing the same into two passages, the partition having an opening in its upper end through which the cream may pass from one passage to the other and being suspended from such end with its lower end separated from the contiguous wall of the churn to establish communication at the lowerportions of the passages, a dasher working in one of the passages to effect acontinuous circulation of the cream through the passages and a feed-nipple for the temperature-regulating liquid.

3. The combination with a churn having a rectangular vertically-elongated body portion, of a hollow partition run vertically through said body por tion near one side thereof and dividing the churn into two compartments, the partition having an opening in its upper portion by which to establish communication between the compartments, an apron covering the opening and projecting downwardly past the same, and means for filling said hollow partition with a liquid for regulating the temperature of the cream.

4. A churn having a vertically-elongated body portion, a partition run vertically in the body portion and having an opening therethrough, an apron carried by the partition and running past the opening to guide the cream in its passage from the opening, and a ledge carried by the partition and capable of engaging a portion of the churn-body to support the partition.

5. A churn, the body portion of which has vertical grooves in opposite side walls, a hollow partition provided with anges beyond its hollow portion and arranged to register in said grooves, a cleat on one wall of said body, and a ledge run out from the partition and resting upon said cleat, wherebythe partition is suspended at a distance from the bottom of the body.

6. A churn having a body portion, a hollow partition within the body portion, the partition being slidably arranged in the body portion and having an opening in its upper portion and through which the cream may circulate, an apron extending from one side of said partition and downwardly past the opening therein, a horizont-al ledge extending from said partition opposite the said apron, and a cleat in said body portion and on which said ledge rests, said cleat holding the bottom of said partition at a distance from the bottom of the body.

7. The combination in a churn having a body portion, of a dasher mounted to reciprecate in said body portion and arranged to force the cream in but one direction, namely, downwardly, and a hollow partition located in said body portion and providing passages at the top and bottom of the body through which the cream lnay be circulated by thereciprocal movement of said dasher, said partition being provided with an inlet-openingl whereby a fluid may be admitted to the interior of the 'same to regulate the temperature of the cream as it is circulated.
